FHWA Updates.Will Stein No news on update of the MUTCD Overhead Arrow Sign Nice from a driver standpoint Length of the arrows should be considered. Example of sign at 494/94 split in Maple Grove St. James Mini Roundabouts Nearly finished. An example with back-in parking. Video timeline can be found here: https://app.oxblue.com/open/srf/signaltoconversion Anoka has the first 5-legged intersection to have a mini-roundabout installed. The pavement markings are non-compliant. Page 1 of 4
2. Requests for Experimentation Update...Janelle Anderson There have been no new requests since February. Reminder that part of the agreement is to provide progress reports to the FHWA every 6 months for the duration of the experiment. There is a possibility that a request could be rescinded if reporting requirements aren t met. New Business 1. Ken Johnson Road Closures for Low Volume Residential Applications (attachment 1) New language was presented for 6F.8, 6F.20, and 6F.68. It was agreed that residential should be changed to local. In 6F.20, with speed limits of 30 mph or less was added. The committee agreed with the changes. Should retroflective pants be required for flaggers during the day? After discussion the committee voted to add this as a shall requirement. STOP/STOP flagger sign (adult crossing area) This item was not discussed will put on October agenda. 6F.50.1 (2C.28) BUMP/DIP language in the MN MUTCD (attachment 2) Janelle Anderson After much discussion it was decided to keep Section 2C.28 language separate from 6F.50.1 language. Ken provided new language for Section 6F.0.1. After discussion revisions were made see attachment for changes. Ken will rewrite. Janelle will rewrite section 2C.28 some of it was missing/incorrect from the last rewrite of the MN MUTCD. BUMP/DIP Field Manual Layout (attachment 3) Device installation and removal language in the Field Manual (attachment 4) The committee agreed to the new language. Page 2 of 4
One Direction Large Arrow Sign new language (attachment 5) Much discussion on this topic. Ken moved to go with proposed new language, Joe 2 nd. Motion failed. Discussion: Why not take the arrow off the 2 nd Type 3 at the end of the taper? Using two Types 3s with arrows gives a conflicting message. Remove arrow above 2 nd barricade unless the 1 st barricade can t be used. Need to do research into this further. The Large Arrow is being used for 3 different messages: Merge Stay over Lane closed Joe moved to adopt the new language striking and end of the merging taper. Scott 2 nd. After discussion Joe withdrew motion. Discussion continued regarding the use of the arrow to delineate a change in horizontal alignment which is allowed (see pg 2C-12 of MN MUTCD). What is considered change in horizontal alignment? Shifting traffic to another lane? Will will ask what the feds consider a change in horizontal alignment. It was noted that Section 6F.69 Direction Indicator Barricades uses the arrow: 6F.69 Direction Indicator Barricades STANDARD The Direction Indicator Barricade shall consist of a retroreflective One-Direction Large Arrow (W1-6) sign mounted above a diagonal striped, horizontally aligned, retroreflective rail (see Figure 6F-7). The One-Direction Large Arrow (W1-6) sign shall be black on an orange background. The stripes on the bottom rail shall be alternating orange and white retroreflective stripes sloping downward at an angle of 45 degrees in the direction road users are to pass. The stripes shall be 4 inches wide. The One-Direction Large Arrow (W1-6) sign shall be 24 x 12 inches. The bottom rail shall have a length of 24 inches and a height of 8 inches. OPTION The Direction Indicator Barricade may be used in tapers, transitions, and other areas where specific directional guidance to drivers is necessary. GUIDANCE If used, Direction Indicator Barricades should be used in series to direct the driver through the transition and into the intended travel lane. Field Manual review dates The rewrite of the Field Manual is underway with a goal of publishing by January 2018. Ken will be asking the committee to review sections of the document as Page 3 of 4
they become available. The Field Manual Committee would like to have the document ready for printing by late November. 2. MN MUTCD Correction 7D.5 Operating Procedures for Adult Crossing Guards (attachment 6) Janelle Anderson The committee agreed with deleting the sentence and shall be used as shown in Section 6K (the Field Manual) of this Manual from the second paragraph of 7D.5. The statement should have been removed with the 2010 rewrite. 3. AWARE Work Zone Intrusion System (attachments 7,8) - Scott Poska Ran out of time to be included in October agenda. 4. Recreational or Cultural Interest Guide and Symbol Signs Heather Lott TEO Signing Committee - 2005 MN MUTCD Section 2H.9.1 needs to be placed into the current MN MUTCD Chapter 2M.

Road Closures for Low Volume Residential Applications (Road Work, Block Parties, etc) The MN MUTCD is pretty definitive on closing roads see below (from MN MUTCD 6F.8): 6F.8 ROAD (STREET) CLOSED Sign The ROAD (STREET) CLOSED (R11-2) sign should be used when the roadway is closed to all road users except contractors' equipment or officially authorized vehicles. The R11-2 sign should be accompanied by appropriate warning and detour signing. The ROAD (STREET) CLOSED sign should be installed at or near the center of the roadway on or above a Type III barricade that closes the roadway (see Section 6F.68). However, some may consider this excessive for work on a low volume residential street or even a block party for which vehicular traffic is prohibited. There may also be a concern for block parties or other situations where the road is only closed to vehicular traffic, for which this language is too prohibitive (all road users). A few thoughts: Should other channelization options (suggested: Type II barricades) be allowed for low volume residential streets? Per previous MCUTCD meeting added option for Type I barricades. Should an option be added for which the sign is used to close the road to only vehicular traffic? Should an option be added to not require the installation of a ROAD CLOSED AHEAD warning sign prior to a road closure on a low volume residential street? Per existing MN MUTCD language, on a low volume residential street, the warning sign with distance is required just prior to the road closure. Possible language for consideration by the committee: Add to 6F.8 The ROAD (STREET) CLOSED (R11-2) sign may be used to close a roadway to vehicular traffic except for officially authorized vehicles. On low volume local streets, the ROAD (STREET) CLOSED (R11-2) sign may be installed on a Type I or Type II barricade. Deleted: residential In 6F.20 (on page 6F-13) After The ROAD (STREET) CLOSED AHEAD (W20-3) sign should be used in advance of the point where a highway is closed to all road users, or to all but local road users. Add the following The ROAD (STREET) CLOSED AHEAD (W20-3) sign may be omitted on low volume local streets with speed limits of 30 mph or less. Deleted: residential Deleted:. kej 170908
Road Closures for Low Volume Residential Applications (Road Work, Block Parties, etc) In 6F.68 (on page 6F-38) After Type II or Type III Barricades should be used on freeways and expressways or other high-speed roadways. Type III Barricades should be used to close or partially close a road. Add the highlighted language to the following Type I or Type II Barricades may be used to close or partially close a low volume local street. Deleted: residential Type I, Type II or Type III Barricades used at a road closure may be placed completely across a roadway or from curb to curb. kej 170908
Road Closures for Low Volume Residential Applications (Road Work, Block Parties, etc) Proposed final language for 6F.8 (added language highlighted in blue): 6F.8 ROAD (STREET) CLOSED Sign (11-2) The ROAD (STREET) CLOSED (R11-2) sign should be used when the roadway is closed to all road users except contractors' equipment or officially authorized vehicles. The R11-2 sign should be accompanied by appropriate warning and detour signing. The words BRIDGE OUT (or BRIDGE CLOSED) may be substituted for ROAD (STREET) CLOSED where applicable. The ROAD (STREET) CLOSED sign should be installed at or near the center of the roadway on or above a Type III barricade that closes the roadway (see Section 6F.68). STANDARD: The ROAD (STREET) CLOSED sign shall not be used where road user flow is maintained through the TTC zone with a reduced number of lanes on the existing roadway or where the actual closure is some distance beyond the sign. The ROAD (STREET) CLOSED (R11-2) sign may be used to close a roadway to vehicular traffic except for officially authorized vehicles. On low volume local streets, the ROAD (STREET) CLOSED (R11-2) sign may be installed on a Type I or Type II barricade (see Section 6F.68). Deleted: residential Proposed final language for 6F.20 (added language highlighted in blue): 6F.8 ROAD (STREET) CLOSED Sign (11-2) The ROAD (STREET) CLOSED AHEAD (W20-3) sign should be used in advance of the point where a highway is closed to all road users, or to all but local road users. STANDARD: The ROAD (STREET) CLOSED sign shall have the legend ROAD (STREET) CLOSED, XX FEET, XX MILES, or AHEAD. The ROAD (STREET) CLOSED AHEAD (W20-3) sign may be omitted on low volume local streets. Deleted: residential kej 170908
For MCUTCD consideration. The existing language in the MnMUTCD related to BUMP and DIP signs has some inconsistencies and didn t incorporate much of the 2009 Federal MUTCD language. This section has been rewritten to include the relevant Federal language and to include language that supports the Field Manual layout. See attached proposed TYPICAL BUMP/DIP SIGNING layout that has been put forth by the Field Manual Update Task Force. This was written to be included in Section 6F.50.1 and to have language to support the TYPICAL BUMP/DIP SIGNING layout (in TTC applications), thus there is inclusion of: advance warning for advisory speeds down arrow at the location of the rise or depression suggested applications of ROUGH ROAD and BUMPS signs If placed in 2C.28, some elements should likely be omitted. There is no DIP AHEAD sign, so the BUMP AHEAD sign is proposed to be used as an equivalent. If the Committee prefers, a DIP AHEAD Minnesota only sign could be an option. 6F.50.1 (or 2C.28) BUMP and DIP Signs (W8-1, W8-2) GUIDANCE BUMP (W8-1) and DIP (W8-2) signs should be used to give warning of a sharp rise or depression in the profile of the road. STANDARD: The DIP sign (W8-2) shall not be used at a short stretch of depressed alignment that may momentarily hide a vehicle. Such a condition shall be treated as a no-passing zone (see Section 3B-2). Only one supplemental plaque shall be permitted beneath each sign. A short stretch of depressed alignment that might momentarily hide a vehicle should be treated as a nopassing zone when center line striping is provided on a two-lane or three-lane road. When the BUMP (W8-1) or DIP (W8-2) sign is used, the BUMP AHEAD (W8-1a) sign with an Advisory Speed (W13-1P) plaque should be placed an adequate distance in advance of the site(s) to ensure that a motorist has sufficient warning before arriving at the location. At the site of each bump or dip, a 45 Degree Supplemental Arrow (W16-7mP) plaque should be added below the BUMP (W8-1) or DIP (W8-2) sign to identify the exact location of the bump or dip. When there are multiple bumps of lesser severity or pavement breaks for a distance in excess of one mile, the ROUGH ROAD sign (W8-8) should be used. The BUMP AHEAD (W8-1a) sign with an Advisory Speed (W13-1P) plaque may be omitted if the determined advisory speed is 10 mph or less than the regulatory speed limit. kej 170906
A flashing beacon or orange flag may be used on the BUMP or DIP sign assembly depending on the severity of the bump or dip. At less severe or multiple bumps, a BUMPS (W8-1b) sign may be placed an adequate distance in advance of the site(s) to ensure that a motorist has sufficient warning before arriving at the location. An appropriate distance plaque, XXX FEET (W20-100P) or NEXT XX MILES (W7-3aP) may be placed below the warning sign. The NEXT XX MILES (W7-3aP) plaque may be used below the ROUGH ROAD sign (W8-8). kej 170906
Field Manual January 2018 NOTES: 1. Multiple bumps should use ROUGH ROAD sign. 2. When a dip, use DIP signs. 33 May use STEEL PLATE AHEAD sign (W8-24) when bump is caused by steel plate. 44 Use on two-lane, two-way roadways. 55 For multi-lane divided or one-way road only. 66 May be omitted if the posted advisory speed is 10 mph or less than the posted regulatory speed. 3 4 6 A 7/28/16 Layout OK MCUTCD review needed 4 5 A 3 5 6 3 6 TYPICAL BUMP/DIP SIGNING 3 DAYS or LESS LAYOUT 73 6k-126
Field Manual Temporary Traffic Control General Guidelines Device Installation and Removal Language Installing the Temporary Traffic Control Zone Traffic control devices shall be installed in the order that drivers will see them, starting with the sign or device that is furthest from the work space. If traffic in both directions will be affected, such as work in the center lanes, the devices may be placed in both directions at the same time. When one direction of traffic will be directed into the opposing lanes of traffic, all traffic controls for the opposing traffic should be installed first. A clear lane at least 10 feet wide shall be maintained at all times. After the temporary traffic control zone is inplace, it should be inspected by driving through the zone. Motorists actions and reactions should be noted and any problems encountered should be quickly corrected. Any modifications to the Temporary Traffic Control Plan or standard layouts and the reasons for the modifications should be documented. During the life of a Temporary Traffic Control zone, maintenance of devices is frequently needed. On short term operations, vehicles may knock over cones which then need to be placed upright. Problems encountered should be corrected immediately and documented. Removing the Temporary Traffic Control Zone Traffic control devices should be removed as soon as the work is completed and they are no longer needed. Devices should be removed in the opposite order from which they were installed, especially devices in the Termination, Activity, and Transition Areas. Devices which the driver sees last should be removed first. Devices in the Advance Warning Area may be removed in the order that they were installed. Alternatively, devices may be removed in the order that they were installed if removed utilizing a Mobile Lane Closure. Crossing Live Lanes of Traffic Personnel may cross live traffic lanes only if it is safe to do so utilizing a walking pace taking into consideration roadway geometry, traffic volume, and other appropriate factors. kej 170906
6F.50.3 One-Direction Large Arrow Sign (W1-6) SUPPORT: For temporary traffic control applications, the One-Direction Large Arrow sign (W1-6) is intended to indicate horizontal alignment changes and to identify tapers. A One-Direction Large Arrow (W1-6) sign may be used either as a supplement or alternative to Chevron Alignment signs in order to delineate a change in horizontal alignment. A One-Direction Large Arrow (W1-6) sign may be used to supplement a Turn or Reverse Turn sign to emphasize the abrupt curvature. An arrow board may be used in lieu of a one direction large arrow for a Temporary Traffic Control Zone. STANDARD: For temporary traffic control applications, the One-Direction Large Arrow sign (W1-6) shall be black on orange background. If used to indicate a horizontal alignment change in temporary traffic control applications, the One-Direction Large Arrow sign shall be installed on the outside of a turn or curve in line with and at approximately a right angle to approaching traffic. One-Direction Large Arrow signs (W1-6) should be used to identify shifting and merging tapers in temporary traffic control applications. To identify shifting tapers, a One-Direction Large Arrow sign (W1-6) should be placed on or above a Type III barricade at the end of the shifting taper. To identify merging tapers, a One-Direction Large Arrow sign (W1-6) should be placed on or above a Type III barricade at the beginning of the merging taper. Deleted: and end For low speed temporary traffic control applications, the One-Direction Large Arrow sign (W1-6) and Type III barricade may be omitted at the beginning of a merging taper. Add language something like if barricade can t fit on the shoulder you can place it at the end of the taper? Add if 45 mph or greater use flashing arrowboard in lieu of one-direction large arrow..? kej 170906
